Application filed December 16, 15 20. Serial No. 431,102.'

-Be it known that I, MARSHALL Low, a citizen of the United States, and a resident of Wilkinsbur in the county of Allegheny and State'of Pennsylvania, have invented a new and useful Improvement in Radiators for Transformer Tanks, of which the following is a specification.

My invention relates to heat-dissipating devices and it has particular relation to apparatus of the above desi atedcharacter that is adapted for containing electrical or other-apparatus normally immersed a cooling medium. More specifically, my invention relates to sheet-metal radiators of the type adapted to be mounted upon ,the outside of a tank or other container and in communication therewith for dissipating heat from the fluid 20 contained therein. 0

The object ofmy invention is to provide a radiator of novel construction that shall be relatively light in weight, simple inconstruction, and inexpensive to manufacture.

Heretofore, it has been customary to construct radiators by connecting together two spaced common header members by means of pipes or tubes. The header members comprise inner walls provided with a er-" tures adapted for the reception of said tu es. An objection to such construction is that it is impossible to vary the amount of radiating area thereof after the installation has been efiected.

Another object is that, in carrying1 repair parts, it is necessary to" carry ha of the header member, as well as a number" of the tubes adapted to be disposed ,there"-' between. I By means of my invention, I provide a type of radiator in which the amount. of

radiating space may be varied at will, either; 4 before or after the erection of the appa-I ratus, Another advantage is that each; radiator section comprises a plurality-got like units and each of the-units-is -con-' structed of two like parts. Thus, the repair parts to be carried in stock may be of a single standard type only.

Figure l of the accompanying drawin s is a view, partially in section and partial y in side elevation, of a portion of a transformer tank having mountedlthereon several units of a radlator constructed in accordance with my invention.

2 is a front elevational view of one of two similar segments, which, when united, constitute a unit of the radiator.

Fig. 3 is a side elevational view of the segment illustrated in Fig. 2.

Inthe drawings, I show, a portion of the wall of a tank 4 and 'a plurality of radiator units 5 mounted thereon. Each of the radiator units consists of two like pressed-metal members 6 which are so bent, that, when fastened together, they constitute a centrally [disposed vertically-extending chamber 7 ends of the passa eways-8 and 9 by means of which eachad acent unit :is attached to the next adjacent unit. The entire segment ,6 is pressed'from a single piece of sheet metal.

thereof bymeans of which the twoco-operatingsegments are welded together to form a unit. Each of the segments is also pro vided with flanges -11 surrounding the outer Any desired number of the units 5 may be i I connected to form a radiator each of the units being supported upon the next adjacentfunit. A tubular member'12 having a coupling member 13 mounted thereon is attached to the innermost unit of each radiator, by means ofthe flange 11. The.

The laterally extending chambers 8 and Q9 of the outermost units of each radiator may be closed by means of a disk 15 of sheet, metal which'may be welded to the flange 11 in the usual manner.

From {the foregoing description, it will be, apparent to those skilled in the art that a'flfradiator constructed-in accordance with my invention will be strong and rigid by reason of the fact that the end portions of each unit are integral with the central portions thereof. Also, it .is apparent that the amount of radiating surface of the radiator may bevaried at will by merely attaching orde'taching any desired number of units.

I claim as my invention: 1. A radiator consisting of a plurality unit.

of units each comprising a sheet-metal men? ber pressed to provide a longitudinally-extending passageway merging into a laterally-extending passageway adjacent to each end thereof, said laterally-extending pasof the longitudinally-extending chambers of adjacent units being spaced apart and the walls of the laterally-extending chambers being attached to the wallsofthe next adjacent 3. A radiator comprising a plurality of heat-dissipating units, eachof said units comprising a plurality of complementary sections having a central channel portion and end channel portions extending transversely to said central portion, said central and end portions being respectively provided with outwardly extending flanges adapted to be exteriorly welded to similar flanges on the coacti'ng sections to provide a unit having a substantially tubular central portion communicating at each end with transverse tubular header portions, the end portions of said sections being also providedwith fiangesdisposed in planes transverse to the planes otsaid first mentioned flanges and adapted to co-operate with each other when said sections are secured to gether to provide continuous flanges adapted to be secured to similar flanges-provided on an adjacent unit.

In testimony whereof, I have hereunto subscribed my'name this 7th day of Decem ber, 1920. a MARSHALL LOW.
